When you do 27 times x squared times z all over -3, then times that by x squared times z to the sixth power, you get -9x^4z^7
Answer:
y = -4
Step-by-step explanation:
3y - 2(5y - 7) = -9y + 6 (Given)
3y - 10y + 14 = -9y + 6 (Distribute)
-7y + 14 = -9y + 6 (Add like terms)
2y + 14 = 6 (Add 9y on both sides)
2y = -8 (Subtract 14 on both sides)
y = -4 (Divide 2 on both sides)
You can check by substituting the solution for y:
3(-4) - 2(5(-4) - 7) = -9(-4) + 6
-12 - 2(-20 - 7) = 36 + 6
-12 - 2(-27) = 42
-12 + 54 = 42
42 = 42
Answer:
Pizza: 27°
Curry: 108°
Fish and Chips: 63°
Kabab: 27°
Other: 135°
Step-by-step explanation:
Frequency 40 = 360°
Pizza (3) =
* 360° = 27°
Curry (12) =
* 360° = 108°
Fish and Chips (7) =
* 360° = 63°
Kabab (3) =
* 360° = 27°
Other (15) =
* 360° = 135°
27 + 108 + 63 + 27 + 135 = 360
